$BTC price changes mainly because of market volatility, leverage, and supply–demand shifts. Crypto markets move faster than traditional markets, so even a small buying or selling wave can cause big price changes. In futures trading, many traders use leverage; when price moves against them, their positions get liquidated, which pushes the price up or down quickly. Institutional buying or selling, economic news, and interest-rate expectations also affect $BTC . If the market becomes fearful, prices drop; if confidence returns, prices pump. So the difference in your $BTC amount or value is mostly due to price swings and leveraged market liquidations.
